RATCI-IET MECHANISM FOR CEMENT-MIXERS.

To all 107mm it may concern:

Be it known that I, ERNEST H. BRANDT, citizen of the United States,residing at Clermont, in the county of Fayette and State of Iowa, haveinvented certain new and useful Improvements in Ratchet Mechanism forCement-Mixers, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to a ratchet mechanism and has special referenceto a ratchet mechanism adapted to be used upon a portable mixer arrangedto mix the cement as the same is being drawn from one place to another.

The principal object of the invention is to improve and simplify thegeneral construction of devices of this character.

Another object of the invention is to provide an improved means forattaching the mixing box to a vehicle axle so that the box will berotated by the rotation of said axle.

With these and other objects in view this invention consists in certainnovel combinations, constructions, and arrangement of parts as will behereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is a section taken transverselythrough the axle. Fig. 2 is a rear view of the machine. Fig. 3 is a viewof a clutch device used herewith.

In the construction of this machine there is provided an axle 1O whereonare revolublv mounted wheels 11, each of said wheels being provided witha hub 12 having a hollow chamber 13 formed therein. On the axle arecollars 14 and on each end of the axle 10 there is provided a cap nut 15and the hub 12 is so arranged as to slide between the collar 14 and thiscap nut. Bearing on the inside of each collar is one end of a-coilspring 16 the other end of which bears against the flange 17 formedwithin the hollow portion of the hub. This hub is provided on its innerface with a series of ratchet teeth 18 which engage ratchet teeth 19formed on a clutch member 20. Supported on the clutch members 20 is abox or casing 21 provided with a hinged lid 22 and having the usualhasps 23. On each end of this casing is a pair of parallel strips 24:

since the spring 16 holds the ratchet teeth 18 carried by the hub 12 inengagement with the ratchet teeth 19, carried by the clutch 20, as thespring 16 bears at one end upon the flange 17 and at the opposite endupon the collar 14. For the purpose of driving the device from place toplace a draft frame 26 is secured to the cap nuts 15 and to this draftframe is attached a pole 27 carrying the double tree 28 to which issecured the swingle trees 29 so that horses may be attached to thedevice.

In operation the receptacle is partially filled with a mixture ofcement, sand, and broken stone or such other mixture as may be desiredand this mixture is mixed to a suitable degree. The device is thenplaced in the place desired to deposit the material and as it movesalong the box will be rotated with the result that the contents will bethoroughly mixed. By reason of the provision of the bar and parallelstrips at each end there is no danger of the receptacle working loose onthe axle as the leverage given the bars 25 at their outer end, as saidbars extend for a considerable distance beyond said axle, is sufficientto prevent loosenv ing of said receptacle. Before arrival at the placeof deposit the vehicle is stopped with the box in an up-side-downposition. If it is not in exactly the right place it may be backed inplace as the ratchet mechanism will allow such movement without turningthe box as the vehicle is backed, the lid may then be unlatched and thecontents dumped where desired. There has thus been provided a simple andeliicient device of the kind described and for the purpose specified.

Having thus described the invention What is claimed as new, is

A clutch of the class described comprising a primary and auxiliarysection, a shaft fitting over one end of one section of said clutch forlimiting the lateral movement of said last mentioned section upon saidshaft, a collar carried by said shaft for limiting the inward movementof said last mentioned section upon said shaft, gripping teeth formedupon the respective sections of said clutch, ,said last mentionedsection of said clutch provided With an inwardly extend- In testimonywhereof I hereunto aflix my ing flange along its inner end, and a spiralsignature in presence of two Witnesses. spring engaging said collar onsaid shaft ERNEST H. BRANDT. and said last mentioned flange for urgingWitnesses: an inward pressure upon said last mentioned F. H. WETZEL,section of said clutch. F. S. BURLING.
